AFter reading about mpm-prefork/worker/event options, I notice that my system has defaulted to mpm-prefork. So i went into webmin>servers>apache webserver>configure apache modules:
Are the following two mod_php? php7.0 php7.3
php7.0 was not checked, however php7.3 was
I unchecked php7.3 and also prefork, then checked worker...however,
after then clicking "Enable Selected Modules" my system returns the following error...
systemctl status apache2.service

my apache error log has the following entry for this time...

I cant restart webserver.
Obviously, once i return settings to what they were before hand, apache restarts no problem.
After i restored the original module settings and then started apache (about 15 minutes later), I then notice the following in webmin>system>system logs>apache2/error.log

Line 45 of /etc/apache2/sites-available/0-domain.com.conf reads
php_admin_value engine Off
So, what is wrong with "php_admin_value engine off" in relation to disabling mod_php?
why cant i disable this? None of my domains, as far as i can tell are using mod_php. I have not selected it for any virtual servers in virtualmin>server configuration>website options (all are running fcgi)
Also, if i follow this outline...http://crazed.io/2013/05/virtualmin-and-enabling-apache-mpm-worker/
I no longer get the errors above, however, wordpress websites on the virtual hosts running wordpress stop working with the same error (static html sites keep running)
Service UnavailableThe server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
apache log when i try to then access a wordpress website returns

What is now causing the 503 error?

is there no one who has an answer on this?
There must be some kind of standard on this that works...I am running Debian 9
